The Operating System gives you two modes of BASIC operation:

- DIRECT Mode
- PROGRAM Mode

- When you're using the DIRECT mode, BASIC statements don't have
line numbers in front of the statement. They are executed whenever
the
`<RETURN>`key is pressed. - The PROGRAM mode is the one you use for running programs.
